An object of the present technology is to provide a semiconductor film capable of further improving photoelectric conversion efficiency. Provided is a semiconductor film containing semiconductor nanoparticles and sulfur, the semiconductor nanoparticles having a core-shell structure, the core portion containing a compound represented by the following general formula (1), the shell portion containing ZnS, and the sulfur and the Coordination of semiconductor nanoparticles. [Chemical formula 1] Cu y1 In z1 A1 (y1+3z1)/2 (1) (In the general formula (1), y1 satisfies the relationship of 0<y1≤20, and z1 satisfies the relationship of 0<z1≤20, and A1 represents S, Se or Te). |
